# vaken — regenerate badges derived from Cargo.toml facts.
#
# Only the badges whose text is derived from a source-of-truth file are
# regenerated here:
#
#   - version.svg → Cargo.toml [package].version
#   - license.svg → Cargo.toml [package].license  (formatted "X / Y")
#
# Platform ("macOS") and maintenance ("passively-maintained") are
# editorial choices, not derived facts — change them by editing
# .github/badges/*.svg directly (or regenerating via generate-badge.sh).
#
# CI runs this script and `git diff --exit-code .github/badges/`. If
# the committed badges drift from the regenerated ones, CI fails with
# a hint to re-run this script and commit the result.
#
# Usage: ./scripts/update-badges.sh
